ABSTRACT:

Botanical classification:
Zoyzia matrella×Zoysia japonica.
Variety denomination: ‘Royal’.
BACKGROUND OF THE INVENTION
This invention relates to a new and distinct perennial zoysiagrass cultivar identified as ‘Royal zoysiagrass’, referred to herein as ‘Royal’. ‘Royal’ is the result of a natural open pollination of material clone TAES-2175 (e.g., K-151). The seedling progenies from the material line were vegetatively increased and tested in a replicated field trial at the Texas Agricultural Experiment Station, Texas A&M University, Dallas, Tex., beginning in 1985. In 1990, several exceptional entries were selected from among the trials, one of which was designated as DALZ9006, which was later named ‘Royal’. The inventive variety exhibits a fine texture typical of
Z. matrella
-type clones such as ‘Diamond’ (U.S. Plant Pat. No. 10,636), ‘Cavalier’ (U.S. Plant Pat. No. 10,778) and ‘Emerald’ and is useful for home lawns, golf course fairways, tees, green surrounds, recreational sports areas or other applications that involve mowing heights from 1.0 to 5.0 cm.
For purposes of registration under the International Convention for the Protection of New Varieties of Plants (“UPOV”) and noting Section 1612 of the Manual of Plant Examination Procedures, the new variety of zoysiagrass of the present invention is named ‘Royal’.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to a new and distinct asexually reproduced variety of perennial zoysiagrass between 1 to 3 years of age (
Zoysia matrella
(L.) Merr)×
Z. japonica
Steud.). The variety name is ‘Royal zoysiagrass’ and is characterized by its purple anthers, white stigmas, an absence of leaf blade hairs and high turf quality among other unique characteristics, all of which are maintained when propagated asexually.
The novel features which are believed to be characteristic of the invention together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures.
